Airport Runway RepairBack to
||Transport Canada Northbay Air Terminal|
||Transportation Air Terminal|
The broken concrete on the aprons at this air terminal required immediate repair. Loose concrete could easily damage aircraft engines, windshields and other critical components. Previous method of repair was to apply cold tar to damaged areas. Cold tar offered only a temporary repair often failing after only 3 to 4 months of service.
All loose concrete was mechanically chipped away. Remaining solid concrete was roughened to provide a profile. Repair area was then chemically cleaned using Cleaner Blend 300. Ultra Quartz was applied using a concrete trowel replacing all missing concrete. Acetone was used as a thinning agent to smooth, blend and feather Ultra Quartz following gel point. Customer now uses Floor Patch Fast Cure (90 minute functional cure) to reduce runway downtime.
